Hey guys 455 which cyl is #1 driver or passenger front? What main and rod journal dimensions fior standard crank? I gotta mike mine thanks?
#1 cylinder is front cylinder on the driver's side. Odd numbers on driver's side, even numbers on passenger side. Firing order is 1-8-4-3-6-5-7-2 :TU:
One head is always mounted ahead of the other head in a V-8 engine. The #1 cylinder is always the farthest forward cylinder. On the 350 and 455's, it is the driver's side front. The cylinders are numbered according to their attachment to the crank front to rear.
That's what I always thought.In a Pontiac, 1,3,5,7 is still on the left, but the right head is farther forward.
Guys thanks again!!! I've got a lot of exp w Pontiacs fords and Chevys, 0 w a Buick, I know these seem like really basic questions, but it's info I just don't know, and once I get these basics down I'm going to be wide open, thanks!!! If I can ever figure out how to add pics and videos to a post I'll share my build!!!
Not always..... :Smarty: I prefer this image that I created the other day. After all, we are an international board :laugh::laugh::laugh::laugh: Not so long ago, a very wise man said this:
That is very strange. That would mean that the #1 cylinder is actually the second one connected to the crank
...and creates no end of problems when lazy machinists install the pistons backwards on the connecting rods due to the non-typical numbering vs. geometry of the Pontiac engine.
OMG, i can tell you stories, stamp the pistons stamp the rods, come back 2 weeks later, backwards just like a sbc, this happened at every shop i ever tried thru the years, forced me to start buying new rods and pistons that float so i could do it myself,
An easy fix for that issue is a simple dot punch on the front beam of the rod before the old pistons are pressed off. Takes what? a total of 3 mins, and that includes the time to pick up a hammer and find a center punch. Just attention to detail. But saves frustration on the customer, and cost to the shop as far as labor to R&R the pistons again, and the cost of a set of pistons. Personally, I do not trust press fit pistons that have been pressed off. They can distort, crack or bust.
